The Verizon MAP list isn't always right and unfortunately, the proof of this can be seen with the Samsung GALAXY Nexus. Originally thought to be coming to market on November 10, U.K. newspaper The Telegraph says it has heard from Samsung that the first Android 4.0 flavored smartphone will be launched in the States one week after the November 17th launch in Britain. A poster on Phandroid's Android Forums who claims to be a Verizon insider, says that because of the lack of Verizon's bloatware on the phone, the carrier has decided not to push too hard for its launch. The November 24th launch is not written in stone and a launch could actually take place later than that date.
